The Supreme Abode of Lord Visnu is effortlessly attainable for the surrendered souls –

“This ocean of material existence is as insignificant as the water in a cow’s hoofprint to those persons who have taken full refuge in the supreme shelter – the boat of the lotus feet of Lord Sri Krsna, whose glories are universally sung as purity’s own self. Their destination is the Lord’s supreme abode, never this mundane abode of calamities.” Bhagavatam, 10.14.53
